How to Get Air Out of a Subaru Cooling System
To get air out of a Subaru cooling system, you can follow these steps:
1. Remove the highest heater hose: Start by removing or not fitting the highest heater hose in the system.
2. Fill the system: Fill the cooling system until coolant comes out of the hose that was removed.
3. Reconnect the heater hose: Reconnect the heater hose that was removed.
4. Use a funnel system: Fit a funnel system with the correct cap to the radiator or header tank.
5. Open the funnel tap: Open the funnel tap and fill the system with coolant.
6. Squeeze the radiator hoses: Continually squeeze the top and bottom radiator hoses to force trapped air into the funnel. This process may take around 5 minutes.
7. Start the engine: Start your Subaru engine and turn the heater temperature up to the maximum, but keep the fan speed to a minimum.
8. Check for warm air: Warm air should be coming out of the heater vents. If not, there may still be air trapped in the system. In that case, stop the engine, allow it to cool down, and repeat step 2 above.
It’s important to note that these steps are based on suggestions and experiences shared by Subaru owners and enthusiasts. Always consult your vehicle’s owner’s manual or seek advice from a qualified technician for specific instructions related to your Subaru model.
